Title: Method and apparatus for underwater tree cutting and retrieval
Inventor: MOSSMAN STEWART
IPC: A01G23/08
Filed: 2001-07-13
Granted: 2009-05-12
Abstract: The invention relates to an apparatus and method for cutting submerged trees at an underwater logging site and for retrieving the cut trees. Once cut, each tree is retrieved to the water surface by an inflatable bag deployed from and inflated by the apparatus. The apparatus includes a control unit positioned on a surface vessel, such as a barge or large boat, and an underwater vessel connected together by an umbilical. Preferably the underwater vessel is a remotely controllable submersible including a grapple for releasably holding each tree to be cut, a saw, a gas supply connectable to a gas source located on the surface vessel, and an air bag deployment and inflation assembly for inflating the air bag and securely attaching it to the tree. The underwater vessel is initially loaded with a plurality of air bags which are stored in a magazine located in the interior of the vessel. The air bags are sequentially moved from the magazine on to an ejection track at a front end of the vessel disposed above the saw and grapple. Each air bag is secured to a cartridge for coupling the bag to the magazine and the ejection track and for holding a tree fastener. In its uninflated state, the air bag is contained within a tubular housing which is releasably connectable to the cartridge. The housing is ejected from the cartridge when the air bag is inflated and deployed.

Abstract: A work vehicle is provided with a brake system actuated by depressing either the left pedal or the right pedal. The brake system comprises two parallel brake circuits. The first brake circuit has a first brake actuator, a first hydraulic line, a first flow regulating portion of a tandem brake valve and a first accumulator. The second brake circuit has a second brake actuator, a second hydraulic line, a second flow regulating portion of the tandem brake valve and a second accumulator. To equalize the hydraulic pressure applied to the first and second brake actuators, an equalizer hydraulic line having an orifice extends between the first and second hydraulic lines. A force feedback hydraulic circuit is hydraulically positioned between the first and second hydraulic lines. The force feedback circuit comprises a first force feedback hydraulic line, a second force feedback hydraulic line and a force feedback hydraulic actuator. The first feedback line extends between the first and second hydraulic lines. The second feedback line extends from the first feedback line to the feedback actuator. The feedback actuator is mounted to the tandem brake valve. The first feedback line is provided with a shuttle check valve having a first inlet, a second inlet and an outlet. The first inlet is in fluid communication with the first hydraulic line and the second inlet is in fluid communication with the second hydraulic line. The outlet is hydraulically coupled to the second feedback line.

Title: Constrained socket for use with a ball-and-socket joint
Inventor: ALBERTORIO RICARDO
IPC: A61F2/32
Filed: 2001-10-19
Granted: 2009-04-07
Abstract: An improved constrained socket for use with an orthopedic implant for replacing a ball-and-socket joint. The constrained socket includes cuts extending from the opening of the socket generally toward the articular region thereof. Petals are formed between adjacent cuts in the socket. The socket further includes an annular expansion cutout, with the aforementioned cuts terminating therein. The socket does not include cuts on the primary articular surface, but nevertheless has a relatively low assembly force to allow assembly of the ball-and-socket joint during a surgical procedure. The relatively low assembly force of the constrained socket of the current disclosure is due in part to the annular expansion cutout which allows sufficient outward flexure of the petals to allow insertion of the ball of the ball-and-socket joint. The ball-and-socket joint of the current invention further includes a locking ring with an interior annular beveled surface to facilitate operable positioning of same and with an exterior visual indicator to facilitate identification of the beveled end of the locking ring. The exterior visual indicator comprises an exterior annular protrusion against which axial force may be supplied for positioning the locking ring about the acetabular cup. In one exemplary embodiment, an acetabular liner incorporates the features of the current invention.

Title: Deck system
Inventor: KEARFUL ROBERT G
IPC: E04F15/16
Filed: 2000-01-21
Granted: 2008-07-15
Abstract: A deck system including cooperating plastic planks (110), fastener covers (112) and end caps. Each of the plastic planks has at least one channel in the upper surfaces which extends the length of the plank. Each channel includes at least one pair of opposed ledges. Each fastener cover is configured for insertion into one of the portion and a pair of legs downwardly depending from the upper face portion and extending substantially the entire length thereof. The fastener cover includes a pair of upper laterally projecting flanges and a pair of lower laterally projecting flanges. When a fastener cover is inserted into a channel, the pairs of upper and lower flanges receive the at least one pair of ledges with a gap sufficient to accommodate displacement of the fastener cover arising from ice expansion in the channel. Such a gap minimizes the likelihood of damage of the fastener cover and/or its expulsion from the channel as a consequence of ice expansion in the channel.

Title: Key telephone system, key telephone, interface unit, and transmission scheme determination method
Inventor: NIIYA NORIMASA
IPC: H04Q3/58
Filed: 2001-12-10
Granted: 2008-10-07
Abstract: A new key telephone system including a new key telephone and new telephone interface which use a new data transmission scheme has been developed, unlike an old key telephone system including an old telephone and old telephone interface unit which use an old data transmission scheme. The new telephone interface unit and new key telephone are compatible with both the new and old data transmission schemes. Even if, therefore, the new telephone interface unit is connected to the old key telephone, or the old telephone interface unit is connected to the new key telephone, data transmission can be performed by using the old data transmission scheme, thus maintaining compatibility.

Abstract: Une composé combustible solide fait de marc de café et ou de déchets de grains verts de café, de sciure et d'un liant de cire est utile pour la fabrication de bûches produisant plus de flamme. Cette combinaison de particules solides et de cire brûle avec le grésillement et le crépitement habituels des bûches de bois naturelles.

Title: Method and apparatus for determining an algebraic solution to gps terrestrial hybrid location system equations
Inventor: VAYANOS ALKINOOS HECTOR
IPC: G01S19/03
Filed: 2000-12-07
Granted: 2009-10-20
Abstract: A method and apparatus for use in a hybrid position location system. The method and apparatus combines measure-ments from Global Positioning System (GPS) and terrestrial transceiver stations to compute the location of a device. An algebraic solution to hybrid position location system equations is output from the method and apparatus. The method and apparatus determines the position of a device using a non-iterative method, as against the use of a conventional iterative least mean square method. The method of the present invention can be used to solve the location system equations in scenarios where a non-iterative solution is desirable. In certain scenarios, the location system equations may have two possible solutions. An iterative method would converge on one of the solutions, without any indication of the existence of the other ambiguous solution. Moreover, the iterative method may converge on the incorrect of the two ambiguous solutions. Use of the presently disclosed method and apparatus yields both the ambiguous solutios. The disclosed method may be followed up with iterative methods, using the solutions from the algebraic method as initial estimates of the device location for the iterative method. A  different process can then select the correct solution. Thus, the algebraic method can be used to detect the existence of ambiguous solutions, and to find both solutions.
